We live in a 2 bed mid terrace and are expecting our 2nd child. We really don't want to move from the street we are in and are being beat to the post by buy to let investors in buying a bigger house in the same street. We are now wondering if it would be possible to extend out the back to create a larger kitchen and 3rd bedroom. Also does anyone know if it is possible to put a glass roof in one of the bedrooms with regards to fire safety etc? Thanks
